MEMOLUB HPS User manual

The MEMOLUB® HPS (High Pressure System) is both an
advanced design, highly accurate, single point automatic
lubricator and a low cost miniature central lubricating system.
It operates as a battery powered self-contained lubricator.
Models are also available that use an external 4.5, 12 or 24DC
volt power source. MEMOLUB® can operate under its own
program control, under control of the machine being
lubricated or a PLC.
The MEMOLUB® Multi-Point System can be used to lubricate
between 2 and 12 lubrication points. Using pipe or tubing, the
MEMOLUB® HPS can be mounted remote from the bearing
being lubricated (see page 4 for details). This feature is
valuable when it is necessary to lubricate hard to reach
bearings, to avoid extremely high temperatures, harsh or
hazardous environments or when mounting the MEMOLUB®
HPS away from excessive vibration.
When operating as a self-contained lubricator the MEMO
programming system controls the frequency of lubricant
ejection cycles. The MEMO also controls the volume of
lubricant ejected on each output cycle when the MEMOLUB®
is operating as either a self contained lubricator or under
external control.
General
Installation
On first installation, use a hand grease gun and the same type
of lubricant to pre-charge all fittings, lines, the bearings. The
MEMOLUB® HPS positive displacement pump has been
primed before shipment and is ready for use. If, however, the
pump becomes unprimed due to running the lubricator
without an empty lubricant cartridge, or operating the
lubricator without a cartridge in place, it should be primed
MEMOLUB® HPS will operate successfully at temperatures up
to 120°F (49°C). Areas of high temperatures can often be
serviced by remote mounting the MEMOLUB® HPS using
pipe or tubing. If constant low temperatures (i.e. -4°F (-20°C)
or lower) are encountered, low temperature approved greases
and MEMOLUB Cold Weather Battery Packs should be used.
The Cold Weather Battery Pack should always be used when
using the MEMOLUB® HPS Giga (Model 480) at temperatures
lower than 32°F (0°C).
The test function should be used on a regular basis when
working under extreme temperature conditions. The shelf life
of a battery pack stored at 68°F is 2 years. Only MEMOLUB®
battery packs should be used in the MEMOLUB® HPS
lubricator.
Batteries
before installing the new lubricant cartridge. This step does
not need to be repeated when changing the MEMOLUB® HPS
lubricant cartridge. To prime the pump, using a hand grease
gun, pump grease through the upper valve of the MEMOLUB®
HPS until grease comes out of the bottom outlet. Two pumps
of grease is generally sufficient. The "Check Function" (page
2) can be used to insure that the pump is primed.
The MEMO has a ¼" NPT thread. It can be adapted to other
thread sizes using standard adapters. Commonly used
adapters are listed on the Installation Parts and Accessories
sheet.
MEMOLUB® HPS is a fully self-contained electro-
mechanical lubricator utilizing a patented positive
displacement pump.
The main components are a motor, gearbox, piston
pump, microprocessor. A cam fitted to the outlet
gear drives a lever which lifts the hollow piston and
simultaneously compresses a spring. When the
piston reaches the top of its stroke, the lever is freed
from the cam and the piston begins its downward
(working) stroke, driven by the spring. Lubricant is
drawn into the chamber formed above the piston
during its downward ejection stroke preparing it for
the next cycle.

Lubricant Cartridges
When installing replacement lubricant cartridges always
install a new battery pack. Lube cartridges and battery packs
are always sold together as a Replacement Kit. Lubricants
available for use in the MEMOLUB® HPS have a weight of
NLGI 2 or lighter. It is recommended that in cold applications
lubricant with an NLGI 1 or lighter be used. MEMOLUB® HPS
with oil filled cartridges should be installed with a Check Valve
(Part Number CV-2). When placing a grease filled cartridge
onto the pump inlet, remove the plug and compress the
cartridge slightly until grease appears at the outlet. Please
see the Replacement Kit Instruction sheet for step by step
instructions for installing both oil and grease cartridges.
Turn on/turn off
The MEMOLUB® HPS is an electromechanical device.
Operation begins instantly when it has been turned on. The
MEMOLUB® HPS may be turned off and back on later if a
machine is taken out of production and put back into use at a
later date. To turn off the MEMOLUB® HPS, simply unscrew it
1 turn. To turn it on, screw it back down onto the MEMO (hand
tight).
MEMOS - Setting The Output Rate
Memos are the method used to set the output
rate of the MEMOLUB® Lubricator. Once
programmed, the Memo is screwed into the
bearing and remains there until it is decided to
change the output rate. The MEMOLUB®
Lubricator is screwed onto the Memo. This
turns on the lubricator to eject lubricant at the
desired rate.
Memos are supplied with 3 colored plastic rings
(black, white and red) and a black plastic ring
holder. The timing of lubricant ejection cycles is
determined by which ring or combination of
rings are placed in the ring holder. The number
of ejection cycles per day determines the
volume of lubricant entering the bearing. With
each cycle, 0.63 cc's of lubricant are injected
into the bearing. The rates of daily lubricant
output using different ring combinations are
shown in the following chart.
The operation of the MEMOLUB® HPS can be tested using
the "Check Function". Simply back off the MEMOLUB® HPS
¾ turn from the MEMO and then turn it back down, hand tight.
The MEMOLUB® HPS will immediately go through an output
cycle.
"Check Function"
The MEMOLUB® HPS is a complete miniature machine with
electronics, electrical motor, gear box and piston pump.
Corrosive, wet environments will damage the MEMOLUB®
HPS even though it is sealed. Hostile environments can be
easily achines are corroded and rusty and
electrical or electronic equipment will generally not be found
installed in the area. The MEMOLUB® HPS must be
protected from corrosive, wet or aggressive environments. It
should be placed in a protected environment (use piping) or
enclosed in a protective cover.
identified as m
Corrosive Environment
The MEMOLUB® HPS gearbox is a relatively heavy unit and
is fitted to the plastic housing. Vibrations will cause it to
oscillate in the housing (similar to fretting) and this, with time,
will generate play and failure. In cases of vibrations,
especially high frequency, remote mount the MEMOLUB®
HPS with flexible tubing or install on the application using a
Vibration Mount Adapter.
Vibrations
Avoid corrosive or
agressive media.

To open the MEMOLUB® HPS, place the pump body on a flat
surface, press the transparent housing downward with one
hand while the other hand squeezes the “rippled” part of the
locking ring, turning it counterclockwise. The ring is now
unlocked and the transparent housing will easily lift off.
When closing the MEMOLUB® HPS, grasp the rippled part
of the locking ring and turn the locking ring clockwise until it
clicks into the locked position. Important: Always test that
the housing is in the locked position by turning the housing
counter-clockwise. When installing the MEMOLUB® HPS
Lubricator, screw the MEMOLUB® body onto the memo by
gripping only on the smooth part of the locking ring.
Opening & Closing the MEMOLUB®, Mounting

The MEMO fitting is permanently
screwed into the grease inlet,
mounting bracket or progressive
distribution block. Its upper bore is an
extension of the MEMOLUB® HPS
piston cylinder. Adding special
MEMOLUB® HPS washers into this
bore shortens the working stroke of the
piston and thus reduces lubricant
output.
One, two or all of the colored timer
rings are selected and placed in the
black MEMO timing ring holder. This
controls the micro switches on the
base of the unit, thus selecting the
frequency of the lubrication cycle.
The MEMOLUB® HPS Output Chart
shows the timing ring and number of
washers required to program any of
the 50 available output rates. The
output rates that are outlined in boxes
are those most frequently used.
Black Ring Steel Washers
Memo Ring Support
White Ring
Red Ring
In many lubrication situations, the lubricant
output rates available using the timing rings
alone will meet the application requirement.
In applications where you want to "fine tune"
lubricant output, it is possible to adjust the
volume of lubricant ejected on each cycle.
Preprogrammed MEMOs may be specified
at time of order. When ordering
preprogrammed MEMOs, please indicate
MEMO Programming
The locking washer counts as one
washer. Always install the locking
washer in the MEMO last where
multiple washers are required. If only
one washer is called for, use the
locking washer. The programmed
output rate may be changed at any
time by pushing the washers back out
of the MEMO and changing the
number of washers used.
The MEMO normally remains on the
lube point when the MEMOLUB® HPS
is removed for replacement of the
lubricant cartridge and battery pack.
In relating the output of the
MEMOLUB® HPS to manual
lubrication practice, generally one
stroke from a hand grease gun is equal
to 1cc of grease.

Remote Installation - Pipe & Tubing
Pipe or tubing may be used with the MEMOLUB® HPS to reach
remotely located lubrication points or those in high
temperature, dangerous or hazardous areas. The maximum
length of piping that should be used is shown in the chart.
When using greases with heavy base oils, the piping length
should be reduced. If there is a question about the base oil
viscosity (ISO) of a particular lubricant, PLI will provide this
information upon request.
This chart assumes that an NLGI #2 grease is being used and
that the application is operating in an ambient temperature of
68°F or warmer. At colder temperatures, pipe length should be
reduced.
In all cases, pipe, tube, fittings and distribution blocks (if used)
should be filled with the correct lubricant before installing the
MEMOLUB® HPS. The best rule for remote installation is not to
over do it, but to mount the MEMOLUB® HPS using the shortest
route possible.
